INVENTOR ATTORNEY Patented May 3, 1932 PATENT OFFICE AUGUSTIN BLZQUEZ, OF CENTRAL BAGUANOS, CUBA VEHICLE TIRE Application led May 31,

This invention relates to tires for automobiles, motor cycles, and the wheels of other vehicles and more particularly to a filler of a resilient character to take the place of the ordinary inflatable inner tube. It is a well known fact that an inner tube presents numerous disadvantages in that it is liable to become punctured thus necessitating repairs requiring considerable time and labor., and, l in the event of any fracture of the casing, is liable to suer a blow-out with possibility of accident and the injuries resulting therefrom, and therefore the present invention h as as its general object to provide a filling unit which 35 may be arranged within the ordinary tire casing and which will possess none of the undesirable features and disadvantages of a pneumatic tube and which will at the -same time possess the desired degree of resiliency so as to insure of even and smooth running of the vehicle, equipped therewith, over road surfaces.

Another object of the invention is to provide a resilient ller unit for tire casings embodying means to preclude any creeping of the unit within the casing or any distortion of the unit, even under severe strains due to high speed of travel or sudden application of brakes. y

Another object of the invention is to provide a filler unit for pneumatic tire casings, to replace the inner tube, which unit may be manufactured and placed upon the market in the form of an elongate body, straight in ently packed for shipment and stored for sale than if of annular form.

This invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter more fully described, illustrated in the accompanying drawings, and specifically pointed out in the appended claims, it being understood of course that minor changes may be made so long as they fall within the scope of the claims.

In describing my invention in detail, reference will be had to the accompanying drawings, wherein like characters denote like or form, so that the units may be more conveni- 1930. Serial No. 458,390.

corresponding parts throughout the several views, and in which Figure l is a vertical sectional view illustrating a tire casing in which the unit embodying the invention is arranged, the unit being shown in elevation.

Figure 2 is a detail vertical sectional view through the unit and casing, the view also illustrating the rim upon which the casing is mounted.

Figure 3 is a detail sectional one coil of the unit.

Figure t is a detail fragmentary View partly in section and partly in plane illustrating the means for connecting the ends of the unit so that the ends may be readily connected and separated.

The unit comprising the invention is in the nature of a helical spring of uniform diameter throughout its length, which spring is indicated in the drawings by the numeral l and is of course formed of steel wire. In order to, prevent any frictional contact of the metallic coil with the inner surface of the tire casing, the helical coil is coated, throughout its entire length, with a coating 2 which is of soft rubber. TheV tire casing is indicated in the drawings by the numeral 3 view through and does not differ from the ordinary casing, and the numeral 4 indicates the usual ller strip which is placed between the beads at the inner side of the casing 3, and the rim upon which the casing is usually mounted is indicated by the numeral 5.

These parts are of course of the ordinary Vconstruction but, as above stated, the inven- `tion contemplates a filler for a pneumatic tire casing which will take the place of the ordinary tire and it 'will be observed by reference to Figures 1 and 2 of the drawings that the filler comprising thespring l and the coating 2 is to be arranged within the tire casing 8 in the same manner as is the ordi- .nary pneumatic tube. ln order to connect the ends of the unit, the unit is provided at one end of the coil, comprisingthe same, with a member 6 which is in the nature of a cylindrical cap including a rim7v and a head :8 about which the rim extends, and the rim is struck in, at a point in its circumference,

12 is mounted upon the socket member and seats in part in saidopening llandlsif,de.-` signed, by its resiliency to be normally closed.

The other member which is mounted at'- the'- other end of the coil is indicated in general by the numeral 13 and'is'of the same construction as the member 6 vexceptthatinstead of'the socket 10, it is providedwith aspher# calhead 14 connectedby aneck 15 with vthe head of the member 13, centrally thereof.`

The headS of the member; 6. is provided with an opening 16 locatedv axially thereof and this opening` is of a` diameter to permit of passagel of the. head 1.4` therethrough. These parts constitute the membersy of a snap fastener connection and it will be evidentthat in bringing themembers 6 and 13 together, these component parts ofthe, fastener will be mutually inter-locked and the filler body will then assume the annular form: shown in Figure` 1 of the drawings. At this point it willbe understood that when they two ends ofthe unit are broughttogether, the ball and socket connection; will serve to hold their ends inr mutually inter-lockedrelation, and therefore the unitwill assume the annular forma adapting it to be fitted into the casing 3' and as the rim 5. is of theordinary split type,rit can becontractedand then permitted to expand so. as to close theinner side vof the casing 3'.V

In order to preventcreeping ofthefunit within thecasin-g 3, split lringsof a resilient metal,A indicated bythe numeral .17, are. sup,- plied lfto coils of the unit at equidistantly dimensions to fit the inner sides of the coils of the unit against which the element is disposed, and it will be evident that alternate ones of the corrugations will accommodate the inner sides of the coils and the intermediate corrugations will lie between relatively adjacentrones of the coils at the inner sides thereof sofas to prevent both spreading and crowding together of the coils.
